The object of the present invention is the production, by simple andrapid process, of la `waist band curtain having `its component layerssecured together and having aigroove adjacent onev longitudinal edge`thereof.

i In order that the method of the present inventionmay be betterunderstood reference is had to the accompanying drawings, in which: `y pi z Figure 1 is a diagrammatic view in per-I spective showing `heseveral steps ofthe present methody Fig. 2 is a fragmentary perspectiveview of a rolloftrouser curtain -or waist-band madein accordance with`the present invention and andillustratingzthe position of the sameinthe inishedgarment.` I `Referring in detail to the drawings, A indicatesthe waist-band or curtain whichis usually produced in roll form, asindicated canvas 10 or otherstiftening material anda j I"45.

in Fig. 2, and B indicates the garmentor trousers to which the curtainis attached, as shown in Figs. 3 and 4.

- Thegeneral construction of the curtain A is substantially the same asthose generally used and employed, consistinglof a strip of co-extensivestrip of twilled or lining fabric 11. It is `the-usual practice tostitch one edge of the lining, asIat 12, longitudinally to the canvas ata point adjacent one edge and infolding the lining around said edgeofthe canvas, as shown clearly in Figs. 2

1929. `Serial No. 373,397.

and 3, withthe major portion of the lining lying in opposed relation tothe adjacent face of the canvas strip. While the present disclosureshows the" lining and canvas attached as above mentioned, this is notessential and no "partei the invention, because 'it is to be understoodthat the lining and canvasmay be associated inanother or any desired1nan` ner.

`In curtains `of `the above character, it is' found that by adhering theopposing aceof` the lining to the opposingface ofthe canvassubstantially throughout their areas, such as by `pasting or the likethat the lining will present atall timesa smooth surface which will `notpucker nor bulge nor crease with re" spect to the canvas when beingapplied rby the operator. Aside from theneat appearance presented,` thisconstruction admits of quicker production bygreatly facilitating theattachment of the curtain to thegarment be# cause of the Ifactthatl thelining `will not bulge or gather `which requires the operator tointerrupt the attaching operation to straighten out, and, in somecases,to rip the sitching, in `order towremove the bulges and gathers. jThelining and the stifening Ina-` terial are adhered together by pastingwith` an adhesive `and to thisjend the adhesive `or sizing usually`carried by the stiffening member is utilized. p .i Animpressed groove15 is formed in the marginal edge portion 14 of the curtainor `waistbandat a distance inwardlyof said edge, say from one-quarter tothree-eights of,` an inch `from said edge, this groove forming ane'ective andinexpensiv'e means on the curtain i actin asia stitchingguide and a `readily benda leIline of fold greatly iacili-` I tatingtheapplication of the curtain and the `folding of the same along an evenline, which will produce a full rounded appearance at the line oi foldin the `linished garment. j

The curtain above described is made in ac-i i cordance with the presentmethod by leading the waist band A from a suitable source of supply,such for instance as a roll a to a steam jet 17 where the steam isdirected upon the waist band so as toIlnoisten Ior make plastic thesizing or adhesive in the canvas or stiiicc , advance of the steam jet17. From the steam jet 17the curtain. passes between'pressurerollers19'and 20. Theroller 19vis provided with a raised circumferential rib 21on its periphery and the roller 20 is formed with a corresponding groove22^to receive the rib 21, the groove being slightly larger than the ribto accommodate the lthickness of the fabric material so that it will notbe cut.

As the curtainpasses between the rollers 19 and 20, the action is suchas to cause the adhesive or sizing in the canvas 10 to adhere theopposing faces of' the canvas and the lining 11 together, substantiallythroughout this area. At the same time the cooperating rib and groove onthe rollers odsety the curtain adjacent one longitudinal edge thereofYso as to forma relatively deep andA wide groove on itscanvas side and acorresponding rib on the lining side.

curtain while the canvas is in a moist state, due to the steamingoperation, which renders the materials somewhat pliable andfacilitatesthemformation of saidgroove. Asr the curtain vbecomes dry,the groove becomes permanently set therein and remains for an iii- :fdefinite period of time. Y The rollers 19 and 20 may be heated ifdesiringto' accelerate drying of the'curtain or a blast'of hot air 23inay be directed upon the curtain after leaving the rollers.

The curtain thusforined is wound -in roll:

form (as shown' inl Figures 1 and 2), the groove on the .canvas side ofthe curtainfiitting overthe rib on the lining ,side of the curtain sothat the convolutionsof the rollwill no t slip edge-wise with respect-toeach other,

but remain in a neat useable form atlall times.

out of the groove, because even though the line of attaching stitchingWithin the groove is slightly irregular, said relatively wide groovewill permitthe curtain kto bend `evenly along the groove and .present aneven line of fold, although thel line ofattaching stitching may-not beperfectly straight. Itis essential that the lining and stiffeningmaterial be rendered relatively stationary with respect to eachother inthe practical useof they groove -A 1,5, becausev ifgthis were not,V thevcase thegrooves in the canvas and lining would not register during theapplication of the curtain to the garment. As already pointed out, thelining material often shifts with respect to the canvas duringapplication and the line of stitching 16 would not penetrate the groovesof both materials.

After the stitching operation shown in Fig. 3, the marginal portion ofthe curtain is turned upon-itself'and will readily `foldY and breakalong the groove l15 -as-shown in Figs. 3 and 4 in the manner abovedescribed, producing a rounded edge at the line of fold which ives afull neat appearance at the edge ofthe waist opening of the garment.After this operation, the ,curtain and trouser are handledin the mannerlgenerally in practice in the clothing industry. Y

From the above itwill be clear that ayvery desirable and economicalcurtain isprovided wherein the lining material is at all times smoothand presents aV neat appearance, and which is provided with a veryAeconomical meansfacting-as a guide or indicatorfor the line ofvattaching stitching and readily bendabl'elineof fold whicliwill producean even and kneat appearance'even. though the line of As before stated,this groove is'made in theV we claim asfnew and desiretosecure byLetters Patent of the United States is:

'1. A method of producing a waist band curtain which `includes arranginga strip of facing material and a strip of stiii'ening material inopposed` face-to-face relation adhering the opposed surfaces of saidstrips together with an adhesive materialin a moist condition Ybypressing said strips of material together and-offsetting said stripsalong one longitudinal edge thereof to form a depressed groove. thereinwhile Vsaid strips are in. a moist condition whereby the groove becomesset-.in the fabric materiall when in a substantiallyA dry condition.V I

2. The herein described method of, producing trouser waist bands whichincludes advancing in superposed relation a sized stiffening fabric anda lining fabric, moistening the stiffening fabric torender the sizing,taclry; then subjecting the advancing strips to pressure Whilemoistened to cause them to adhere throughout their contacting areas andosetting, while moist, a port-ion of the stiffener strip to provide agroove yin one face thereof and an-opposed rib on its other faceextending along one longitudinal edge thereof, said groove constitutinga visible follow line for the operator when stitching thewaist band tothe trouser material and an easy bending line of fold.` l

3. TheA herein described method ofV 'producingtrouser waist bands whichincludes advancing in superposed relation a sized stiii'ening fabric anda lining fabric, subjecting the stiiener `fabric to action of steam to irender the sizing\tacky; then subjecting the advancing strips topressure `While moistened to `cause them to adhere throughout theircontacting areas and ofsettlng, while moist, a portion of the stiienerstrip to prop `vide a groove in one face thereof and an opposed rib onits other face extending along one `longitudinal edge thereof, saidgroove i constituting a visible follow line for the operator whenstitching the waist band to the trouser material and an easy bendingline of fold.
